The identifier 'Binary:Wix4UtilCA_X86' could not be found

[guenhter]

Hi,

I used this tutorial https://wixtoolset.org/docs/tools/wixext/quietexec/ and created a wxs file containing exaclty the block of the instructions:

<SetProperty
  Id="WixQuietExecCmdLine"
  Value="&quot;[%ComSpec]&quot; /c ECHO %NUMBER_OF_PROCESSORS%"
  Before="ConvolutedCoreCountCustomAction"
  Sequence="execute"
  />
<CustomAction
  Id="ConvolutedCoreCountCustomAction"
  BinaryRef="Wix4UtilCA_$(sys.BUILDARCHSHORT)"
  DllEntry="WixQuietExec"
  Execute="immediate"
  Return="check"
  />

<InstallExecuteSequence>
  <Custom Action="ConvolutedCoreCountCustomAction" Before="AppSearch" />
</InstallExecuteSequence>

but when building the msi, the following error appears

> wix build .\package.wxs -o my.msi
C:\Users\...\package.wxs(25) : error WIX0094: The identifier 'Binary:Wix4UtilCA_X86' could not be found. Ensure you have typed the reference correctly and that all the necessary inputs are provided to the linker.

I've installed Wix via dotnet tool install --global wix

> wix --version
5.0.0+41e11442

any idea what I'm doing wrong?

I think you need the util nuget package. You didn't say what wix version but here's one for Wix5: https://www.nuget.org/packages/WixToolset.Util.wixext

I'm using

> wix --version
5.0.0+41e11442

but not a .net project. I'm creating Wix without any msbuild or thelike but just via cli. When I run the command:

> dotnet add package WixToolset.Util.wixext --version 5.0.0
No project found in "C:\foo\".

Maybe as additional background: Ultimatively I just wanna call a external scrpt to run this single line:

schtasks /create /f /tn "%TaskName%" /tr "%BatchFilePath%" /sc hourly

Hmm, there's an artifacts zip on the wixtoolset release section containing all the nugets. Nugets packages can be open like zip files and contains the dlls. Guess you could get it from there.

I only used MSBuild and I don't know of a way to download nuget package without a project.

Read the parent topic in the documentation: WiX extensions and custom actions

Thanks. This helped.

Is it possible to have a custom action then for installing and another one for deinstalling?
